为研究矿井水中有机污染物的潜在风险，针对矿井水中的已知有机污染物，使用EPI Suite和毒理学数据对其持久性、生物累积性和急性毒性进行系统模拟和评估，并采用层次分析法（AHP）基于毒性效应和环境效应的2个一级指标及7个二级指标建立矿井水中优先有机污染物的评估体系。研究结果表明：①54种有机物中有13种持久性物质、8种生物累积性物质及1种急性毒性物质, 其中卤代烃的持久性最强, 多环芳烃的生物累积性最强, 与羟基自由基(OH•)反应的反应速率的总体趋势为: 醚＞酯＞卤代烃；脂肪族＞芳香族。(短链卤代)脂肪族化合物没有生物累积性物质, 多环芳烃的生物累积性普遍较高，且生物累积性物质分子结构中均有4个及以上的苯环, 苯环个数的增加会导致多环芳烃生物累积性增强。磷酸三苯酯为显著急性毒性物质, 需要在后续的矿井水处理中重点关注。②筛选出综合评分最高的20种有机污染物作为矿井水中的优先污染物, 其中评分较高的二氯甲烷、1, 2−二氯乙烷、甲苯、邻苯二甲酸二丁酯、邻苯二甲酸二(2−乙基己基)酯、萘、苯并[a]芘、二苯并[a, h]蒽、苯并[b]荧蒽、苯并[k]荧蒽和苯并[a]蒽符合新污染物特征，但目前矿井水中已经测出的有机污染物存在水平普遍不足以对人体健康和生态环境造成显著风险。随着国家政策实施和矿井水高质量处理利用需求的增加，矿井水中有机污染物的管控将成为区域水资源保护与利用的现实需求，本研究构建的优先有机污染物的潜在风险评估体系可用于筛选出矿井水中优先污染物, 为未来矿井水中有机污染物管控提供理论基础。

In order to investigate the potential risk of organic pollutants in coal mining water, the persistence, bioaccumulation and toxicity of known organic pollutants in coal mining water were systematically simulated and assessed by using EPI Suite and toxicolgical data, and the analytic hierarchy process (AHP) was used to establish an evaluation system for priority organic pollutants in coal mining water based on two primary indexes and seven secondary indicators of toxic and environmental effects. The results showed that: ① there were 13 persistent persistent substances, 8 bioaccumulative substances and 1 toxic substances among 54 organic pollutants, halgenated hydrocarbons have the strongest persistence, polycyclic aromatic hydrocarbons have the strongest bioaccumulation, and the general trend of reaction rate with hydroxyl radicals (OH•) is as follows: ether>esters>halgenated hydrocarbons; aliphatic>aromatic. (Short-chain halgenated) aliphatic compounds have no bioaccumulative substances, and the bioaccumulation of polycyclic aromatic hydrocarbons is generally high, moreover, there were 4 or more benzene rings in the molecular structure of the bioaccumulative ones, and the increase in the number of benzene rings would lead to the enhancement of the bioaccumulation of polycyclic aromatic hydrocarbons. Triphenyl phosphate is a significant toxic substance, which needs to be focused on during coal mining water treatment. ② The 20 organic pollutants with the higher comprehensive score were screened out as priority pollutants in coal mining water, among which dichloromethane, 1,2-dichloroethane, toluene, dibutyl phthalate, di(2-ethylhexyl) phthalate, naphthalene, benzo [a] pyrene, dibenzo [a, h] anthracene, benzo [b] fluoranthracene, benzo [k] fluoranthracene and benzo [a] anthracene have the characteristics of emerging contaminants, however, the level of organic pollutants detected in coal mining water is insufficient to pose risks to human health and ecolgical environment presently, but with the implementation of national policies and the increase in demand for high-quality treatment and utilization of coal mining water. The control of organic pollutants in coal mining water will become an realistic demand for the protection and utilization of regional water resources, and the potential risk assessment system of priority organic pollutants constructed in this study can be used to screen out priority pollutants in coal mining water, and provide a theoretical basis for the future control of organic pollutants.
